To all whom, it may concern.-

Be it known that I, WILLIAM DART SHEP- PARD, a subject of the King ofGreat Britain, residing in Exeter, Devonshire, England, have inventedcertain new and useful Improvements in or Relating to Gas Cooking-Stoves or the Like, of which the following is a specification.

This invention relates to gas cooking-stoves or the like, such ascooking-stoves heated by li uid hydrocarbon burners, (all of which Iwill hereinafter refer as to gas cookingstoves,) and has for its objectto provide new or improved means inside the stove for heating water (orany other liquid desired) from the same source ofheat'or products ofcombustion as thatby which-the cookingstove is heated and atthe sametime as the cooking is being done. The waste heat or products ofcombustion may (if desired) be utilized, as hereinafter described,without consuming more gas (or oil) than is ordinarily used for cookingpurposesi. e., the heating of the water is obtained practically withoutreducing the heat available for cocking purposes, and thus withoutaffecting or interfering with the cooking properties of the stove, and,if desired, an auxiliary burner may be provided for heating the waterwhen the cooking-stove is not required for cooking, and also thisauxiliary burner may be utilview in front elevation (partly in section)of similar construction of gas-stove according to my present invention,but showing a modification with respect to the water-supply andwater-heating arrangement exterior of the stove.

Referring to the accompanying drawings, A is the gas-supply pipe fromany suitable source which conducts the gas to the Bunsen burners A A oneach side of the stove-casing, while gas is supplied independentlythrough the supply-pipe A to the Bunsen burner A across the back of thestove, so that this auxiliary Bunsen burner A may either burn alone ormay be used in conjunction with the burners A A or the latter may Aaccording to requirements. Just above said burner or burners A AfA, Iarrange and mount a boiler B, extending along the two stove-casing insubstantially the same hor1- zontal plane, said boiler being mounted onor supported by means of brackets C, bolted or secured to the sides orwalls of the stove or on any other suitable supports, and any suitablemeans may be employed to keep said boiler B in position on or betweenits supports-as, for example, bolts or flanges on the brackets C, &c.Said boiler may be a four-sided tube, as illustrated, or of rectangularform, or of any other suitable form-for example, oval-shaped incross-section. The form, arrangement, and location of this boiler B isaccording to my present invention advantageously as follows-t. 6., asillustrated in the accompanying drawings, the bottom of the said boilermay be flat (or of any suitable form) and is located close down upon andjust over the gas-burners, (say about one inch between the bottom of theboiler and the top of the burners) and the inside wall or inner face Bof said boiler is advantageously sloped u wardly and inwardly toward thecenter of the stove, so that said boiler is wider (in cross-section) atthe top than at For the sake of example I will describe my inventionwith reference to the accompanying drawings as carried into practice inconjunction with an ordinary gas cooking-stove of the present well-knowntype with a Bunsen gas-burner arranged at or near the bottom of saidstove and extending all round or partly round said stove, and I haveillustrated in the drawings a square upright stove with a Bunsengas-burner, which latter in addition to extending, as usual, along twoopposite sides of the stove may also advantageously extend along a thirdside (say across the back of the stove opposite the door) as a separateand independent burner.

In the accompanyin drawings, Figure 1 is a view in front elevation,partly in vertical section, of a gas cooking+stove having my presentimprovements applied thereto and with a small cistern supported. on abracket upon one side of said stove. Fig. 2 is a plan view of Fig. 1.Fig. 3 is a perspective view of the boiler, partly in section, andBunsen burner, removed from the stove.

the bottom or in such wise that the inside wall of said boiler all roundthe stove will present an inwardly-sloping surface B, against whichlatter the heat from the Bunsen burners will act (to heat the water inthe boiler) as said heat rises in the stove, the water being thus heatedin the boiler practically without interfering with the operation ofcooking in the stove. The Fig. 4 is a form, arrangement, and location ofthis sides and across the back of the rectangular be used alone withoutthe auxiliary burner ICC geously be located boiler B inside the stoveand just above but close down to the Bunsen burner or burners in thelower part of said stove'constitutes a very essential or importantfeature of my present invention, the following being important featuresin connection therewith:

(a) The boiler is so constructed and designed as to be adapted to beplaced in the lowermost part of the stove (just over the Bunsen burners)in such wise that it practically does not reduce the availablecooking-space within the stove. (b) This boiler being provided with theinwardly-sloping sides B and, owing to the location of this boiler B,close to and directly over the Bunsen burners, as illustrated in thedrawings, thereby the water is heated in the boiler practically withoutinterfering with the cooking operation in said stove. (c) The top ofsaid boiler B can, if desired, be utilized as a ledge or means forsupportingagrid or other open-work shelf in the stove. Water issupplied. to said boiler B in any suitable manner and from any suitablesourcefor example, by flow-pipe E and return-pipe F, which pipes areconnected to a cylinder or tank (or other suitable vessel) located atany desired point, either near to or distant from the stove, from which.cylinder, &c., said water can be drawn ofl as and when required, coldwater being advantageously supplied automatically to said cylinder&c.as, for instance, by means of a balland-cock arrangement or bybird-fountain feed, &c.

In carrying this invention into practice I may arrange and mount thewater-supply tank or vessel G, attached to the stove by means ofbrackets II, as illustrated in Figs. 1 and 2, and connect the flow andreturn pipes E F to said tank G and provide adraw-ofl cock G, so that inthis arrengen'ient, as illustrated in said Figs. 1 and 2, the waterwould be fed to said tank G (and boiler) byhand, or, as illustrated inFig. 4, thefeed-water cylinder tank or reservoir I may advantaquiteclose to the stove and be so constructed, arranged, and mounted as to beadapted to heat or warm. the water-supply therein by the waste heat orproducts of combustion coming from the stove, so as thus to deliver warmor partly-heated water to the boiler in the stove, and for this purposethe waste pipe or flue J, through which the products of combustion passout of the stove, tank I, so as to For example, I may is led to the saidcylinder or heat the water therein.

form an annular chamber K between the on t side of the tank I and theouter cylinder or jacket Ii, surrounding the cylinder or tank I, theproducts of combustion being led from the hue J into the annular chamberor space K between said tank and said cylinder ll, or any other suitablejacket arrangement may be employed. After thus utilizing the waste heatfrom the products of combustion same may be allowed to escape through.any suitable outlet M, Fig. 4, which latter may be controlled by avalve, such as N.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is

1. In a cooking-stove, the combination, with a rectangular casing, of aboiler comprising a horizontal tube divided into portions extendingalong and supported on the side *alls and. the rear wall of said casing,said tube having a flat top surface and an upwardly and inwardly slopinginner surface which defines an opening for the nissage of the productsof combustion, and burnertubes arranged parallel to and directly beneaththe side and rear portions of said tube.

2. In a cooking-stove, in coi'nbination, a rectangular casing, a boilercomprising a tube divided into portions which and. are supported on theside *alls and the rear wall of said casing, burners extending beneaththe two side portions of said tube and connected. with the same sourceof fuel, and an independent burner arranged beneath the rear portion ofsaid tube.

3. In a cooking-stove, in combination, a rectangular casing, a boilercomprising a horizontal tube divided into portions extending along andsupported on the side walls and the rear wall of said casing, said tuliehaving a flat top surface and an upwardly and inwardly sloping innersurface which defines an opening lor the passage of the products ofeomlnistion, a gas-supply tube extending across the front wall of saidcasing, burner-tubesconnected to said supply-tube and arranged directlybeneath and parallel to the side portions of the boiler, and anindependent burner-tube arranged beneath and parallel to the rearportion of said boiler.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
